Using multiple Monolog Loggers
|
|
==============================
|
|
|
|
Having separate instances of Monolog for different parts of your system is
|
|
often desirable and allows you to configure them independently, allowing for fine
|
|
grained control of where your logging goes and in what detail.
|
|
|
|
This simple example allows you to quickly configure several monolog instances,
|
|
using the bundled handler, but each with a different channel.
|
|
|
|
.. code-block:: php
|
|
|
|
$app['monolog.factory'] = $app->protect(function ($name) use ($app) {
|
|
$log = new $app['monolog.logger.class']($name);
|
|
$log->pushHandler($app['monolog.handler']);
|
|
|
|
return $log;
|
|
});
|
|
|
|
foreach (array('auth', 'payments', 'stats') as $channel) {
|
|
$app['monolog.'.$channel] = function ($app) use ($channel) {
|
|
return $app['monolog.factory']($channel);
|
|
};
|
|
}
|
|
|
|
As your application grows, or your logging needs for certain areas of the
|
|
system become apparent, it should be straightforward to then configure that
|
|
particular service separately, including your customizations.
|
|
|
|
.. code-block:: php
|
|
|
|
use Monolog\Handler\StreamHandler;
|
|
|
|
$app['monolog.payments'] = function ($app) {
|
|
$log = new $app['monolog.logger.class']('payments');
|
|
$handler = new StreamHandler($app['monolog.payments.logfile'], $app['monolog.payment.level']);
|
|
$log->pushHandler($handler);
|
|
|
|
return $log;
|
|
};
|
|
|
|
Alternatively, you could attempt to make the factory more complicated, and rely
|
|
on some conventions, such as checking for an array of handlers registered with
|
|
the container with the channel name, defaulting to the bundled handler.
|
|
|
|
.. code-block:: php
|
|
|
|
use Monolog\Handler\StreamHandler;
|
|
use Monolog\Logger;
|
|
|
|
$app['monolog.factory'] = $app->protect(function ($name) use ($app) {
|
|
$log = new $app['monolog.logger.class']($name);
|
|
|
|
$handlers = isset($app['monolog.'.$name.'.handlers'])
|
|
? $app['monolog.'.$name.'.handlers']
|
|
: array($app['monolog.handler']);
|
|
|
|
foreach ($handlers as $handler) {
|
|
$log->pushHandler($handler);
|
|
}
|
|
|
|
return $log;
|
|
});
|
|
|
|
$app['monolog.payments.handlers'] = function ($app) {
|
|
return array(
|
|
new StreamHandler(__DIR__.'/../payments.log', Logger::DEBUG),
|
|
);
|
|
};
